Abstract (en)

Transmission system (comprising) an engine (10) which drives a propeller shaft (14) through continuously variable gearing (CVG) (11), split path gearing (12), and a disconnector device (13). <??>In neutral (N) or park (P) operation, the disconnector device (13) receives the drive from the propeller shaft (14). The speed (N0 min ) of the propeller shaft (14) corresponding to the prevailing setting of the CVG (14) is calculated by circuitry (30 to 34) responsive to speed transducers (25, 26). The calculated speed (N0 min ) is compared with the actual propeller shaft speed (N0) in a summing circuit (35), and the output of this circuit provides a control signal via a frequency compensation circuit (36) and an amplifier (49) to an actuator (24) so as to vary the ratio of the CVG (24) to equalise the calculated speed (N0 min ) with the actual speed (N0).
